What do you think are the chances? Human or alien biological components? Who do you want to see most? Let the fanwank begin!

Chances: No frakking idea. TF Prime has already pulled some rather obscure characters in with the way back machine so I think at this point anything is possible, but unless they make a huge departure from the rather limited cast set-up, there would probably only be a few on each side.

Human/Alien: Human. I really don't get the sense that Prime will ever get the story very far from the Planet Earth, so aliens are probably out. I'd love to be wrong about that. Maybe it could be MECH that engineers it or the tech for it can be brought in by a space-faring Transformer(doesn't matter which side as it WILL get stolen by the other).

While I do have an affection for the Head / Target master thing, I wouldn't want it carried over here. However, some type of bonding can happen... I just wouldn't want people to fold their bodies up into uncomfortable positions, upside-down, to become a head.
